Answer:
x= 5.458
Step-by-step explanation:
x+15.92 = 21.378
- 15.92 - 15.92
x = 5.458
Helpful hint: You just have to use inverse opperation to solve these problems
So, basically the opposite of what it is.
0.07 is 7 hundredths, and can be represented as 7/100.
7/20 = 35/100 (or 0.35) 35/100 ≠ 7/100.
Multiplying both the top and bottom by the same number, the ratio will not change, like how one half, 1/2, is equal to two quarters, 2/4.
Given:
To find:

The answer for multiplying polynomials:
To find the width, divide the area by the length.
Width = 375 / 25
Width = 15 feet.
